Summary
Forensic identification is aided by analyzing paranasal sinus dimensions using CT scans. Sinus size varies significantly by sex, but not by age, offering a reliable tool for personal identification.
Area of Science:
- Forensic Anthropology
- Radiology
- Anatomy
Background:
- Fragmented bones pose challenges in identifying individuals after mass disasters.
- Dense bones like the maxilla, with intact sinuses, serve as reliable forensic tools.
- Non-invasive Computed Tomography (CT) imaging aids in evaluating fractures and locating foreign bodies.
Purpose of the Study:
- To estimate dimensions and volumes of frontal (FS), maxillary (MS), and sphenoidal air sinuses (SS) using CT scans.
- To investigate age- and sex-related differences in sinus dimensions and volumes.
Main Methods:
- CT scans of paranasal sinuses from 158 patients (aged 19-73) were analyzed.
- Statistical analysis was performed using SPSS 20, with a significance level of p<0.05.
- Institutional Ethical Committee approval and participant consent were obtained.
Main Results:
- Frontal, maxillary, and sphenoidal sinuses were significantly larger in males than females (p<0.05).
- Overall dimensions and volumes of FS, MS, and SS showed significant sex-based differences.
- No significant age-related correlation was found in sinus dimensions or volumes.
Conclusions:
- CT imaging is a reliable tool for personal identification in forensic anthropology.
- This method can be used in countries where autopsies are not permitted.
- Paranasal sinus analysis provides valuable data for forensic investigations.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
